# outputs
This model is a fine-tuned version of [microsoft/phi-2](https://huggingface.co/microsoft/phi-2) using [trl](https://github.com/huggingface/trl) on [ultrafeedback dataset](https://huggingface.co/datasets/HuggingFaceH4/ultrafeedback_binarized).

# What's new
A test for [ORPO: Monolithic Preference Optimization without Reference Model](https://arxiv.org/pdf/2403.07691.pdf) method using trl library.
